The Sub tuum praesidium is the oldest known hymn to Virgin Mary and is often used in Christian services as a prelude to the Litany of the Blessed Virgin Mary (also known as the Litany of Loreto). In 1944, Tolkien recommended his son Christopher to learn "the Litany of Loretto [sic] (with the prayer Sub tuum praesidium)" by heart[1]. It was therefore logical that Tolkien created his own Quenya Litany of Loreto, which immediately follows in the same manuscript as the Ortírielyanna.[2]
